Twilight Sparkle and Rainbow Dash find themselves drawn by the call of the cutie map to a jungle in the middle of nowhere. Drawn further by the knowledge of an ancient temple, they are confronted with icy cold and a sense of dread.
Another 'Changeling on Earth' story, but it's more directed and less all-over-the-place like Pet Changeling? I really had no idea what I was doing with that one, but I think I could try doing it again with better results.
Also to clarify, it would be about Queen Sanguine rather than a different queen like Blue. Dunno if that would make it more or less appealing.
